cell Definition:The basic building block of life in an organism Context:A cell's major parts ? the nucleus, mitochondria, and other organelles ? have a particular function that ensures that the cell gets the food and oxygen it needs to stay alive. organ Definition:A structure in the body composed of different tissues, each of which contributes to the overall functioning of that organ Context:The heart has four kinds of tissue, all of which ensure that blood is pumped throughout the body. organ rejection Definition:The term used to describe the response of an individual's body to a new organ or tissue that it recognizes as foreign Context:It has taken years of scientific research to find ways minimize the effects of organ rejection on the human body. tissue Definition:A group of similar cells that perform a particular function in the body Context:Epithelial tissue makes up the skin, which protects the body's other organs. tissue engineering Definition:The construction of an organ in the laboratory by using cells from an individual's body grown on a human-made structure called a scaffold and then transplanted Context:Scientists have successfully used techniques of tissue engineering to create skin and cartilage. transplantation Definition:The removal of a diseased organ and replacement with a healthy organ or tissues from another person Context:The first successful kidney transplantation between identical twins took place in 1954 at Peter Bent Brigham Hospital in Boston, Massachusetts. stem cells Definition:A unique type of cell often harvested from embryonic cells that can differentiate into different kinds of cells in the body Context:Although the use of stem cells is controversial, scientists may be able to increase the number of organs produced if a large enough supply is available.

cell
Definition:The basic building block of life in an organism
Context:A cell's major parts ? the nucleus, mitochondria, and other organelles ? have a particular function that ensures that the cell gets the food and oxygen it needs to stay alive.
organ
Definition:A structure in the body composed of different tissues, each of which contributes to the overall functioning of that organ
Context:The heart has four kinds of tissue, all of which ensure that blood is pumped throughout the body.
organ rejection
Definition:The term used to describe the response of an individual's body to a new organ or tissue that it recognizes as foreign
Context:It has taken years of scientific research to find ways minimize the effects of organ rejection on the human body.
tissue
Definition:A group of similar cells that perform a particular function in the body
Context:Epithelial tissue makes up the skin, which protects the body's other organs.
tissue engineering
Definition:The construction of an organ in the laboratory by using cells from an individual's body grown on a human-made structure called a scaffold and then transplanted
Context:Scientists have successfully used techniques of tissue engineering to create skin and cartilage.
transplantation
Definition:The removal of a diseased organ and replacement with a healthy organ or tissues from another person
Context:The first successful kidney transplantation between identical twins took place in 1954 at Peter Bent Brigham Hospital in Boston, Massachusetts.
stem cells
Definition:A unique type of cell often harvested from embryonic cells that can differentiate into different kinds of cells in the body
Context:Although the use of stem cells is controversial, scientists may be able to increase the number of organs produced if a large enough supply is available.
